BUTTONIN GrMACHIN E.

Application filed June 13, 1916, Serial No. 103,446.

To all whom it may concern:

Be it known that I, LEWIS J. BAzzoNI, a citizen of the United States, and resident of Swampscott, in the county of Essex and State of Massachusetts, have invented certain Improvements in Buttoning-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to buttoning machines, and is herein shown as embodied in a machine particularly adapted for use in the manufacture of boots and shoes for buttoning, in accordance with the usual practice, several of the buttons of the shoe upper prior to the assembling and lasting operations in order to. facilitate the proper lasting of the shoe and to insure that the buta ton piece and the buttonhole fly shall be correctly positioned in the finished shoe. It should be understood, however, that the invention, in many of its features and in its broader aspects, is not limited in utility to machines for buttoning shoes nor restricted. to the precise embodiment herein illustrated, but is susceptible of various embodiments and applicable to various uses upon different classes of work.

It will also be apparent from a consideration of the drawings and description that the illustrative machine may be used with equal facility for performing buttoning operations upon finished shoes as well as for buttoning the upper materials of a shoe be fore the shoe is lasted.

The inventionis herein illustrated as em: bodied in a machine for buttoning a'plurality of buttons simultaneously, but it will be apparent from a consideration of the construction and mode of operation of various portions of the illustrative machine that in many of its aspects the invention is not limited to a machine of this particular type.

An object of the invention is to provide a buttoning machine of simple construction in which the work may be quickly arranged in position for buttoning and which will perform the buttoning operation in a rapid and efi'ective manner.

Specification of Letters Patent.

Patented July 23, 1918.

Renewed March 26, 1918. Serial No. 224,887.

Important features of the invention reside in novel means for effecting relative move ment between a button and the material adjacent to a buttonhole to perform a buttoning operation with respect to the button. The construction shown provides buttonhole fly engaging means constructed and arranged for wiping engagement with the material at opposite sides of a buttonhole to effect a progressive movement of the material into buttoned position, said means, in the illustrative construction, being movable longitudinally of the buttonhole.

A further feature of the invention consists in novel means for insuring the disposal of the material adjacent to a buttonhole in buttoned position under the head of a button. For this purpose the invention in its illustrative embodiment, provides buttoning means for forcing the material adjacent to a buttonhole under the head of a button and means for positioning the button in such manner as to permit it to be lifted by the buttoning means. comprises means movable relatively to the material of the buttonhole fly to press it toward buttoned position and to lift the button to facilitate the disposal of the material under the edges of the button head.

Another feature of the invention consists in novel means for opening a buttonhole for the reception of a button, the construction shown comprising means movable longitudinally of the buttonhole in spreading engagement with the material at the edges of the buttonhole.

The above and also other features of the invention, residing particularly in novel work positioning and work ejecting means and in various novel details of construction and combinations of parts, will now be described with reference to the accompanying drawings and pointed out in the claims.

Themachine comprises a plurality of sets :of cooperatinginstrumentalities, each set including button and button-hole fly posi- "tionin g means and abuttoning device. Each set has its own independent support, and

the several supports are mounted for relative' movement to conform to differences in the spacing of buttons and buttonholes on different pieces of work. In the machine shown there are five sets of instrument-alities, in order to adapt the machine for buttonin'g :five buttons at each presentation of a piece of work, but it will be understood that the machine may include any suitable number of sets, according to the number of buttons-which it may be desired to button.

-A base or frame on which the olfJerating -mechanism is mounted is indicated at 10 and an operating shaft at 11, the frame be- "in-g provided with bearings for the shaft.

A plurality of adjustable button position ing members are indicated at 12, these members comprising forwardly directed forks for the reception of the buttons when the work is initially presented to the machine Each of the members *12 is secured to a separate arm 13, and the several armsare p votally mountedupon an upright rod 1 1 secured in the frame '10. As show-nby Fig. 1', each arm 13 has two separate portions embracing the rod 14-. The two portions of one arm are indicated at 13, those of another arm at 13 those of the third arm at 7 13, and thoseof the fourth at 13 The gfi fthor central-button positioning fork is indicated at 12 in Fig. 2. This fork, as dis- :tinguished from th 'e forks 12, is fiXed-in position, being secured directly to the frame '10. 'T he fiXe'd fork is the middle fork of i the series o'f-five, and inconsequence of this arrangement the relative adjustment of the 6 5*severa l fork-s is simplified.

The forks 12 and 12*, as clearly shown in Figs. 1, 7 8 and 9, receive the shanks of the buttons and support the buttons and the button piece. 011 the drawings a button is indicated at a and the shank at a, theshank' being secured by a staple Z2 tot-he button piece 0 of the shoe, 'gaiter or'other article. The buttonhole fiy is indicated at (Z, and a buttonhole at (Z.

Each member 12 or 12 is slotted, as shown by Fig. '2, to receive a buttonhole fly positioning member 16. Each of the members 16 has an upwardly extending point 1(3 adapted to engage in a buttonhole, as. shown by Fig. 1, to determine the'position of the buttonhole in relationto thecorresponding button. Each member 16 is in the form of a bell-crank and is pivoted at 17 on the member 12 or 12*. The downwardly extending arms of the several members 16 are all engaged by a single operating lever 18,

the latter havingfor this purpose elongated parallel confronting surfaces 18*. As the adjustable elements move. toward or from each other, the downwardly extending arms of the members 16 slide'freely along the sur faces 18 and remain always in cooperative relation to these surfaces. The lever 18 is mounted upon a fulcrum stud 19 and is oscillated by a path cam 20 secured to the shaft 11 (Fig. A roll 21 carried by the lever 18 engages the cam; 7

The members 16 are in operative position only for a brief time at the beginning of a cycle of'operations. Their function is to determine the position of the buttonhole fly,

and such position having been determined, the first operation of the machine is to depress a clamp member which cooperates with the button supporting forks to clamp the buttonhole 'fiy. The clamp member comprises a work-engaging bar 22 which is supported by arms 22*, one ofsaid arms be-- The points '16 remain depressed, through out the buttoning operation and "until-the work is removed, and are then raised-to their initial positions to receive-the next piece-of work. i

The severallbuttoning devices", hereinafter The p 12o thereafter withdrawn from the 'buttonholes.

described in, detail, are carried by bell-crank levers 27. "Each-adjustable arm an overhanging extension uponwhichismounted a corresponding lever 27, and the bellcrank lover of the middle buttoning device is supported by a stationary overhanging arm which is secured to the base 10. The several bell-crank levers 27 are mounted in their respective overhanging arms by pivot studs 28. The bellcrank levers are all operated in unison by a single operating lever 29 which has elongated parallel confronting faces 29*, the members 27 being free to slide from side to side between the surfaces 29* in the same manner as the members l6 relatively to the lever 18. The operating lever 29 is substantially U-shaped, its two arms being connected by a hub mounted upon a fulcrum rod 30, and a third arm 31 secured to the hub and operated by a cam 32, Fig. 3, this arm having a roll 33 which engages the cam. The direction of operative movement of the buttoning devices is indicated by an arrow in Fig. 1.

The structural details of one of the buttoning devices are best shown by Figs. 4, 5 and (3. Each device comprises a toe portion which is shaped to enter a buttonhole at the beginning of the operation of the device. This portion engages the ma terial at the end of the buttonhole, as shown by Fig. 10, thus insuring the correct relation of the buttonhole to the button in order to facilitate the operations which follow. The head of. the button at this time rests upon the opposite sides of the button supporting fork, being held firmly thereon by the weight of the button piece, and the shank a is seated against the crotch of the fork between the closely adjacent opposite side portions of the fork so that the button will not be displaced laterally to any ma terial extent by the buttoning device. The buttoning device, as a whole, is in thenature of a cam and has a wiping action upon the stock. Two diverging flanges 36 extend backwardly from the portion 35, as shown by Fig. 6. These flanges enter the buttonhole, and engaging the side edges of the lat ter exert a wedging action whereby the sides of the buttonhole are separated beyond the edges of the button head, as shown by Fig. 8. The toe portion 85, after drawing the buttonhole fly over the button as hereinbefore explained, becomes disengaged from the material in consequence of downward movement of the latter which is effected both by an'inclined front edge of the too 35 and by cam shoulders 37- outside the flanges 36, said shoulders being inclined relatively to the path ofinovement of the buttoning device, as shown by Figs. 1, 5 and 10. A passageway 38 is formed in the buttoning device to receive the head of the button while the buttoning device is operating. The rear ends of the flanges 36 are flanged laterally, as at 36*, the inner edges of the flanged portions being constructed to pass under the head of the button and lift the button head from the button supporting fork.

The heel of the buttoning device comprises flanges 3.) which are, in effect, extensions of the flanged portions 36*, and which pass under the head of the button as shown by Fig. 9. The bultoning device, as shown, is made in two parts, the front part being distinct from the rear part. This is to enable one part to be adjusted relatively to the other, as hereinafter explained; but the principle of operation of the device would be the same if both parts were formed integral. In the device as shown, referring especially to Fig. 5, the rear end of the front or toe part abuts against the forward end of the rear or heel part as indicated at 1:0, thebottoin surfaces of the two parts being flush at this point and presenting, to all intents and purposes, excepting that of adjustment, a continuous structure from the front of the toe to the rear of the heel. l Vhile the flanges 36 of the toe part are opening the buttonhole, the shoulders 37 depress the material at the edges of the buttonhole below the edges of the button head, thus clearing a path for the flanged portions 36 and flanges 39 to pass between the head of the button and the button piece and lift the button, as shown by Fig. 9. The bottom surfaces of the flanges 39 offer no obstruction to the closing of the buttonhole, the buttonhole auton'iatically closing under the head of the button in consequence of the tendency of the stock to resume its normal condition. \Vhile the stock would normally close under the head of the button if the flanges 39 were omitted, their use is prefer able in order to insure the proper operation of the device under all conditions. WVhile the flanges 3%) underlie and support the head of the button the operative stroke of the buttoning device ceases and the return stroke begins, the head of the button being thus held elevated for a sufficient length of time to insure the closing of the buttonhole thereunder. The flanges 39 are substantially concentric in relation to the axes of the respective pivots 28, and are not disturbed when the toe piece is adjusted as hereinafter explained.

The purpose of the adjustment of the front or too part of the buttoning device is to adapt the device to the particular height of the button head. A button which has a relatively high head requires a greater depressing movement of the buttonhole fly than a button which has a relatively low head, and in order that the toe part of the device may properly enter the buttonhole on the top of the button head, it .must be adjusted in accordance with the height of the head. As shown by Fi 1-, the toe piece is formed with oppositely projecting flanges 41 which arearranged to slide in complemental grooves 42 formed in the member 27. These flanges and grooves are segmental, be-

,ing concentric to the meeting point 40 of the toe and heel portions. In consequence of this arrangement it is obvlous that the a rear end of the toe portion will merely rock piece.

upon the forward end of the heel portion without causing any separation at said:

point when the flanges 41 slide forward or backward through the grooves 42. The effect of such sliding movement is to raise or lower the toe 35 relatively to the heel and to vary the inclination of the bottom surfaces of the toe member to cause more or less depressing movement of the material.

Any suitable means may be provided for giving the desired adjustment to the toe I have shown for this purpose a nut 43 threaded upon a shank 4a carried by the member, 27. The fee piece has an extension e5 which has cooperative lips l6,the latter embracing the rim of the nut 48 and being movable forward and backward in accordance with the endwise movementof the nut 7 upon the shank.

. which are indicated at 47, one of said arms In determinlng the necessary adjustment of the toe piece, an article to be buttoned will i which discharges the work automatically after the buttoning operation has been completed, this ejector comprising a substantially .U-shaped member the two arms of being partly broken away in Fig. 1. The two arms are connected by a crossbar .48 which underlies all the. button supports.

The ejector is mounted upona-rockshaft 4L9 which is operated by a'cam 50 through an arm '51, the latter having a roll 52 which engages the cam. The crossbar 4C8 lies behindthe shanks or eyes of the buttons and V overlies the button piecec, the arms 47 be ing separated far enough to admit ,thework' between' them. The crossbar a8 is thrown forward by the action of the cam and engages the shanks of the buttons or the fasteningstaples Z), or both, or on some classes of work engages the button piece adj acent to the buttons, and ejects the work in consequence of such engagement and movement.

. hen the work is presented to the ma chine the shanks of the buttons will readily enter the several buttonsupporting forks,

the openings in the forks being relatively Wide at tl r r ard endsandnarrowing The level at which the buttoward the rear. Theseveral arms 13 are .free to move about. the pivot '14 and will ,automatically assume the desiredspaclng in accordance with the spacing of the buttons as the buttons engage the sides of the forks. Anysuitable means, not herein shown,"may be used if. desired to'insure-that the several .sets of operating .instrumentalities shall be spaced equidistant-1y in all positions of adjustment. The points 16 will partake of the adjusting movement of the arms 13 and will therefore be in position to register with the several .buttonholes. The buttonhole fly having been positioned by the points "16, Eas shown by Fig. 1, the work is ready for'the operation of the machine. The first operati'on is that of the clamping device 22 the latter descending until the buttonhole fly is clamped upon the button supports .12 and 12% to hold the fly against the drag or pull of .the buttoning devices. The points 16 descend in time to clear the buttoning devices, but they are not withdrawn from the buttonholes until the buttonhole fly has been clamped. The cam 32 then operates the buttoning devices, the latter beingimmediately retracted when they have completed their 'button'in'g movement. The clamping :device 22 is then raised to release thearticle, and

the .ejectore8. is operated. When the arfticle has .been ejected, the points 16 are raised .to their initial positions and the ejector is.also returned to its initial position. All the elements are thus restored to "their starting positions and the machine is 'readyto receive another plece of work.
